Abstract. Nurani SG, Deluna NN, Nabila P, Falah S. 2022. Effectiveness of gel formulation of mahogany (Swietenia macrophylla) bark extract and its potential as an anti-inflammatory in white male rats (Rattus norvegicus). Nusantara Bioscience 14: 117-121. Mahogany bark contains phytochemical compounds that have anti-inflammatory activity. This study aims to determine the anti-inflammatory activity of mahogany-bark extract gel formulation in-vivo. Gel formulations of 96% ethanol extract of mahogany bark at different concentrations were tested for anti-inflammatory activity on the paws of rats induced by 1% carrageenan. The data observed were the thickness of the foot edema of rats. Positive control was anti-inflammatory drugs (Desoximetasone), and negative control was the gel formulation without extract. Data on the thickness of rat paw edema were analyzed using the ANOVA test. The results of the anti-inflammatory test showed that gel formulation 2 with an extract concentration of 10% had a thickness reduction value of 41.83%, which was not significantly different from the positive control treatment of 44.38%. The results of the dispersion test showed that formulation 2 and formulation 3 had good dispersibility, as suggested in SNI, and all gel formulations had good adhesion. Based on these results, it was concluded that formulation 2 was the most effective in reducing rat paw edema.

Abstract

Antibiotic resistance and biofilm-associated infections remain critical global health challenges. Its responsible for up to 65% of infections in humans and have adaptive resistance 10–1000 times higher against conventional antibiotics. Thus, development and finding of new antibiofilm agent is needed. Marine bacteria, particularly symbion of anemone Heteractis magnifica, offer promising yet underexplored sources of bioactive componds as antibiofilm agents. This research aimed to optimize the growth condition, assess the antibiofilm activities and identify potential strain of symbiotic bacteria from H. magnifica in Samalona Island, Indonesia. The growth of two bacterial isolates (CM01 and CM03) were optimized, revealing that CM01 grew best in TSB with 2%NaCl and 2% peptone at 37°C for 48 h incubation, while CM03 exhibited optimal growth in Zobell medium with 2% peptone at 28°C for 48 h. Secondary metabolites produced under these conditions were tested against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus epidermidis, and Staphylococcus aureus. The 50-hour metabolite of CM03 demonstrated the strongest and broadest antibiofilm activity. Due to its antibiofilm potential, strain CM03 was subjected to genomic characterization using 16S rRNA PCR method. Phylogenetic analysis identified the isolate as Halalkalibacter okhensis. These findings indicate that symbiotic bacteria of H. magnifica, particularly H. okhensis CM03, represent promising candidates for the discovery of new antibiofilm agent.
